Honda-SOHC

Evening chaps

My engine has been stripped and I've had the cases vapour blasted ready for a repaint.All the internals are in excellent condition but a couple of the crank shells are slightly marked.
To be honest they would be fine but as the motor is apart we will replace them as its a no brainer.
Is there some markings on the crank to say what size(colour)are required for replacements,the only marks we can seen anywhere is on the rear of the lower engine case and that is AAAA.

I seem to have hit a bit of a snag.
A couple of weeks ago I ordered a new main loom from dss and it arrived today so I thought I had better check to make sure its right.
I seem to be missing 8 wires at the fuse box end.6 are for the fuse holder and 2 are for small black box at the bottom right corner(not sure what this is,diode maybe?)
So my question is what is the general consensus.Is the loom correct for the model even though I'm 8 wires short and the one on the bike is wrong as is the electrical block.


I've been through the parts,workshop and delivery manuals and can't come up with an answer and it doesn't show the small black box.
I never got the bike running before I started stripping it even though that was the original plan so I can't rule out whether it was correct or not.There are a lot of home done crimps on the bike so it has been tinkered with,any help would be appreciated.

I've had a look at the looms on the dss site and the one for the 550 seems to have more wires and an extra plug,the fuse box plug on my loom has gone and just been crimped

A couple of questions for you knowledgeable chaps.

I've noticed on the parts list there are a left and right spacer that should be fitted to the top yoke.They are between the pinch gap that holds the fork in place.
Are these critical as the're missing from mine? Will a stainless washer(what thickness)be ok or should I use something else.

The second question I've partially answered by reading a thread in the 400 section.I've seen this is supposed to be a steering lock but would iy have been originally keyed a like to the ignition(i know you can't now).Although it's a fairly simple bike by design without an owners manual or any paperwork it's pain knowing it had a steering lock or any other features.

I'm trying to find a way of keeping the original ally right hand switch gear rather than change it for a plastic one.

The problem is I'm missing the front plastic knob and the top rotary dial is in terrible state.
Although the top is seized I should be able to free that once it's off the bars.
Is there any sources you know of that can help me out with a repair or spares?
I see on ebay theres loads of plastic ones that look the same but or for small cc models,I was wondering how interchangable they where or even if I could strip a new one for spare.

Evening chaps.
As the cafe project toodles along I've started to mess with the frame so I now have to decide on what exhaust I need.
I really only want to fit a stainless 4-1 system but the problem is finding one.After spending hours looking I've only found 2 and there both in the US.
I had decided on a Yoshi replica from Lossa Engineering which I was going to order today but in there ultimate wisdom there now only steel not stainless.
The other gut I found in the US won't import to the UK.

Can anyone help?

Morning,recently joined the forum and I thought I start a thread on my project I;ve just started.

CB500 1972 K2 purchased just over 3 weeks ago with the intention of doing a cafe racer build.Unfortunately the bike was in worse condition than I hoped so now its a ground up build rather than a tart up.


First job is to make sure it runs before I take the engine out of the frame.I'm going to have a compression/leak down check done to see the the state of play and then I'll do an oil change if hasn't got to come apart,then clean the carbs.


Carbs off ready for ultrasonic cleaning/servicing.

Ordered my new battery,oil filters,carb servicing kits,master cylinder service kit as that seized solid.
This is state of play as of last night.It will stay like this now until I get the engine checked and carbs cleaned and back together to see if she fires.


Just for comical value,the pile of rust after the strip down
